Friday was payday for the CDC’s employees. Or, rather, half a payday. Employees of the Atlanta-based public health agency received roughly half their pay last week due to the federal shutdown. Workers were paid for the one week prior to the shutdown, but the second week of the pay period was affected by the shutdown.

The government shutdown has damaged the CDC’s ability to detect and prevent disease, the agency’s director said Monday. Roughly 9,000 of the 13,000 employees of the Atlanta-based public health agency have been furloughed by the shutdown.
